Question
Present age of Sunita is 3 times the present age of
Nita. 4 years hence twice the age of Sunita will be equal to thrice the age of Nita. Find the present age of Sunita.Solution
Let present age of Nita = x So present age of Sunita = 3x 4 years hence, => 2(3x + 4) = 3(x + 4) => 6x + 8 = 3x + 12 => 3x = 4 => x = 4/3 Present age of Sunita = (4/3) × 3 = 4 years

{(8× 8 + 3 × 39) - 620 ÷ 20} = ?
[∛(91125/19683 )- ∛(3375/5832 ) ] × ∛(512/9261) = ? - √(484/3969)
84367 + 65441 + 32645 – 21145 – 10769 = ?

√2025 + 35% of 400 = ? (1225/25) - (192/96) + (50/5) = ?
84% of 8400 + 42% of 6120 =?
6 0 - 20 [8 + 12 {8-8 (20-12)+20}-40] ÷ 16 =?
142 + 233 + ?2 – 301 = 450 + 65
